BARBECUED CHOPPED CHICKEN

Steps:

• To prepare the sauce, melt the butter with the oil in a straight-side skillet over medium heat. Add onions and cook until lightly browned. Stir in remaining ingredients, including lemon rinds, and simmer 20 minutes. Remove from heat and discard rinds. For a very smooth sauce, puree in blender or food processor.
• Prepare grill.
• In a large bowl combine chicken and 1 quart of the barbecue sauce. Rub sauce all over chicken, coating well.
• Grill 15 minutes on each side. Remove to a platter and set aside until cool enough to handle. Pull chicken from bones in bite-size pieces. Discard bones. (Skin may be saved if you want a very rich sauce. Set it aside.)
• In a food processor or blender, puree the onion. (If you want to use the chicken skin, puree with the onion.) Warm a large straight-side skillet over medium heat, add the oil, and when hot, add the onion. Cook, stirring frequently, until translucent. Add vinegar, salt, pepper, chili powder and the remaining 1 1/2 quarts of barbecue sauce. Stir well; add the cooked chicken and simmer on low heat 30 minutes.
